IMPROVEMENT IN MACHINERY FOR LAYING ROPE.

Specification forming part of Letters Patent No. 23,491, dated April 5, 1859.

To all whom it may concern.-

Be it known that we, GEORGE W. PITTMAN and WILLIAM C. BooNE,.of Bushwick, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Laying Rope; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which-` Figure 1 is a longitudinal sectional view of a horizontal laying-machine constructed according to our invention. Fig. 2 is a transverse section of one of the'iers.

Similar letters of reference indicate corresponding parts in both figures.

Our invention relates to that description of rope-laying machine whose strand-fliers or two or more of them are arranged with their axes in line with each other.

It consists, first, in a certain method of forwarding the twist of the strands from the fliers which are farthest from the layingpoint.

It consists, secondly, in a guide-ring applied, as hereinafter described, to that one of a series of fliers so combined which is farthest from the laying-block for the purpose of carrying forward toward the laying-block the forehard twist, which is given by the revolution of the said ier to a strand supplied from a spool which turns in fixed bearings outside of the fiiers.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

'A A A2 are three standards constituting the principal portion of the framing of the machine, and containing the bearings for the two fliers BB', from which two of the strands o and c are Supplied, and the standard A2, having attached brackets a, which support the spindle b of a bobbin C2, from which the third strand c2 is supplied. The hollow jour- -nal j', which forms the connection between the fliers, is supported in the middle standard A, and the journals j and 7'2 at the opposite ends of the fliers are supported in the standards A A2.

The fliers are made much longer than the bobbin, in order to prevent short bends in the strands, and the elliptical form shown in the drawings is to be preferred. The flier-bcbbins C C have their spindles d d supported in bearings in iron cradles E E', which are provided with journals ee to it to bearings iu the fliers, the said bearings in the fliers being concentric with the axis of the fliers andthe cradles being heavy enough to hold the bobbins stationary, or nearly so, by gravitation while the fliers revolve. One journal e of each cradle is hollow for the strand to pass through. The flier B contains the laying-block g, and it has two guides h h for the strands c2 o to pass through on the way to the laying-block. 'lhe flier B' has attached to it two guides i and m on one side for the strand o2 to pass through, the guide fml being a single eye, but the guide 'L' being a ring which passes through and plays freely in an eye i', which attaches it to the dier. This ring t' constitutes one feature of our invention and its operation will be presently described.

F is the capstan,by which the rope is taken up as fast as it is laid, supported in bearings attached tothe standard A.

G is the driving-shaft of the machine, supported in bearings in the standards A A A2, and carrying two pulleys l-I and I, the -forxner driving the two fliers by a belt 7c, running over a pulley .T on their connecting journal j', and the other pulleyI driving the capstan by means of a belt L, which passes under two guide-pulleys l l and overa pulley M, attached to the capstan.

The bobbin C2 is so arranged that it will deliver its strand c2 through the hollow flierjournal 72. The said strand passes from the said journal to the ring` 1f, round which it is once turned, and from the said ring it passes through the guide m, and from thence through the journal j and the flier B, and through the guides 71, h in one side of the flier and into the laying-block. The strand c passes from the bobbin C round the bottom of its cradle E', through two guides fn n, attached thereto, and through the hollow journal e thereof, and from thence through the journal j', in which it and the strand c2 take a few turns round each other and into the fiier B, through the guides h h on the opposite side of the said flier to those through which the strand c2 passes, and from thence to the laying-block.

The strand @passes from the bobbin C round other or be, as it' Were, laid and unlaid in the bottom of th-e cradle E, and through guides passing through the said journal, each is made n n thereon through the hollow journal e to .help forward toward the laying-point the thereof, and from thence direct to the layingi additional twist in the other one, and by this lock. means and the use of the ring/i the necessity The operationof laying is produced by the` of gearing for forwarding the twist is disrevolution of the fliers, which gives to the pensed with and the machine greatly simplistrands o c', before they leave their respectd. n, ive fliers, an additional twist; but this twist Instead of having the two lliers connected is taken out in laying, leaving each strand by the journal j', each may have a separate with the same twist it had when introduced journal with a communication from one liier to the machine.
